INTODUCTION

• Substation Automation Systems (SASs) are widely usedfor the purpose of control, protection, monitoring,communication etc. in substations to improve thereliability of the power system.

• SASs adopting IT based solutions such as Ethernet A!have recently become more common.

• Although hardwired control has been used in the past inearlier versions of SAS utili"ing simple communicationmethods.

• #oreover, the IE$%&' standard has been issued as the

new global communication standard for substations.

• The standard consists of ten parts, the *nal part beingissued in +. Subseuently IE$%&' has been appliedwidely in SASs around the world.

,-AT IS IN T-IS PESENTATION• In this presentation, I will describe our

e-perience of an IE$%&' based SAS,including system design and buildmethods.

• In addition, I will also cover conceptsfor system build and detailed systemcon*guration.

•The bene*ts of IE$%&'.

• oints to be considered forimplementation of IE$%&' and issuesthat are e-perienced in practical

application of the standard together
